医用耗材全生命周期一体化智能供应链系统的构建研究OA

Objective:To construct an integrated intelligent supply chain system for full lifecycle of medical consumables,and to explore application value of digital technique in improving efficiency of management for supply chain of hospital.Methods:A hierarchical technical architecture consisting of data layer,network layer,consensus layer,smart contract layer and application layer was adopted.Three mainly functional modules,i.e.,intelligent procurement,dynamic inventory management and full process traceability,were configured to construct the integrated intelligent supply chain system for full life cycle of medical consumables.Data were collected from 3 comprehensive third-level grade-A hospitals of Chongqing,including data of 150 072 surgeries and related data of medical consumables that were used in surgery from January 2023 to December 2024.Among them,the data of 74 316 surgeries from January to December 2023 were assigned as the pre-implementation group,and 75 756 surgeries from January to December 2024 were assigned as the post-implementation group.The average time of consumables requisition,days of inventory turnover,cost of consumable consumption per operation,error rate of billing,and consistency rate between accounts and materials of 3 hospitals between before and after the system was applied were compared,and the change of intervention effects after the system was applied also was compared and analyzed.Results:After this system was implemented,the average time of consumables requisition,days of inventory turnover,cost of consumable consumption per operation and average error rate of billing of combined effect of 3 hospitals were respectively(2.7±0.8)h,(6.8±1.5)d,(10 980.2±1210.7)CNY and(0.8±0.3)％,all of which were significantly lower than those before it was implemented,and the differences were significant(t=35.62,43.75,17.93,40.81,P<0.05).The average consistency rate between accounts and materials was(99.1±0.5)％after it was implemented,which was significantly higher than that before it was implemented(t=29.47,P<0.05).The differences of the decreased degree of the average time of consumables requisition,average days of inventory turnover,average cost of consumable consumption per operation,average error rate of billing,and the increased degree of consistency rate between accounts and materials of intervention effect among 3 hospitals were significant(F=9.05,10.12,13.08,8.27,29.75,P<0.05),which had higher heterogeneity(I 2>50％).Conclusion:The application of the integrated intelligent supply chain system for full lifecycle of medical consumables can improve the efficiency of requisitioning medical consumables,and accelerate the inventory turnover of medical consumable,and control the cost of surgical consumables,and enhance the accuracy of billing consumable,and the level of consistency between account and materials.
